On an old IBM Notebook I have still BeOS r5 running. I noticed that using the Deskbar/Tracker filesearch on BeOS I can click on the top-categories like Name / Path / Size … and the results are getting sorted almost immediately while the search is running, which is very kool.
Even using queries leading to a huge amount of results. I can also rearange the top categories by dragging them left/right to another position. On Haiku it is not as responsive. Afaik the Deskbar / Tracker code is based on the original BeOS source code. I would like to know why there is such a difference. Is it because of the newos kernel, due to the implementation of the GUI toolkit, or is it a matter of multithreading which was changed in the Tracker source code?
I still think Haiku is a very cool OS because it focuses on the vital things which an OS
should provide. But responsiveness is great in my opinion and still KDE does not reach that
level as the BeOS did.
